My friend swears to me that the new Dooney & Bourke Handbags she brings is the authentic Dooney & Bourke Handbags. How can I know she’s telling the genuineness?

You can find inside the Dooney & Bourke Handbags it will have the signature red, tan, and blue Dooney and Bourke, Inc. logo. Also under that tag or label or somewhere in the Dooney & Bourke Handbags it will have the registration number.
